[Filomeno Robles]

Whenusing the hydraulic motor produced by Hanjiu Technology Co., Ltd., some people may find that there are some large and small problems with the motorneeds to hydraulic solutions . At this time, everyone will suspect that the actual product of the Hanjiu brand does not match the publicity, because we promise that the life of the motor is longer than Other brands are longer. But the editor wants to tell you that the service life of the motor is not only related to the quality. According to relevant statistics, the motor failure rate in the market is very high, and there are many failures of the motors of some well-known brands. Therefore, the correct use of the motor is an important factor that directly affects the working life of the motor. If you want to make your motor last longer, please read the following carefully.

After the hydraulic motor is installed, its matching system should be equipped with a corresponding oil filter to ensure the cleanliness of the system oil. The hydraulic circuit must be equipped with a cooling system to prevent excessive oil temperature. Pressure gauges and thermometers must be installed in the oil inlet line.

The pressure gauge should be installed in the hydraulic circuit of the hydraulic pump. There are also some requirements for hydraulic oil. Because of different ambient temperatures and uses, hydraulic oil should have good viscosity, temperature performance, and good defoaming performance, as well as anti-oxidation, anti-rust, high flash point and other functions. Hanjiu Technology recommends that you use YB-N46 and YB-N68 anti-wear hydraulic oil.

If for some reason the hydraulic system is disassembled and needs to be reinstalled, before installation, check the motor for damage, and drain and flush the oil stored for a long time to prevent the internal moving parts from sticking. The motor mounting bracket must have sufficient rigidity to prevent shock and vibration during rotation, and the bolts connecting all parts must be tightened evenly.

It should be noted that the hydraulic motors of the BM series cannot be operated under the working conditions of the pump and cannot be used as a pump. When installing, it should be determined whether the surface is flat, whether the dimensions of the connecting flange, stop point and output connecting shaft are accurate, and ensure that the output shaft and the device connected to the transmission have good concentricity. When installing the output shaft, axial thrust of the output shaft and interlock must be prevented.

Since the motor is a very precise part, you should install it carefully, do not hit the screws and the back cover at the rear of the motor, and do not install it with force or twist it. Do not remove the plastic plug above until piping and tubing are installed.

After purchasing the products of Hanjiu Technology, if you have any unclear questions, you can ask the customer service staff in advance to prevent unnecessary losses.

3. Do not use a hydraulic breaker to peck holes on hard rocks. When breaking tough objects, start from the edge first, and do not knock continuously for more than 1min at the same point, so as to prevent the drill rod from burning or the hydraulic oil from overheating.

4. Do not operate when the piston rod of the hydraulic cylinder is fully extended or fully retracted, otherwise, the impact vibration will be transmitted to the hydraulic cylinder block and then to the main engine.

7. Do not carry out hydraulic breaker operation in water or muddy ground. Except for the drill rod, other parts of the breaker body should not be immersed in water or muddy, otherwise, the piston and other parts with similar functions on it will cause premature loss of the crusher due to accumulation of mud stains.

10. When the hydraulic breaker is installed and connected with the excavator loader or other construction machinery, the working pressure and flow of the hydraulic system of the main machine must meet the technical parameters of the hydraulic breaker. The "P" port of the hydraulic breaker is connected with the high-pressure oil circuit of the main machine, and the "0" port is connected with the return oil circuit of the main machine.

12. The working medium used by the hydraulic breakers can generally be the same as the oil used by the hydraulic system of the main engine. YB-n46 or YB-n68 anti-wear hydraulic oil is recommended for general areas, and YC-n46 or YC-n68 low-temperature hydraulic oil is recommended for cold areas. The filtering accuracy of hydraulic oil shall not be less than 50 μ M.

16. It is not allowed to use the hydraulic breaker as a crowbar to avoid breaking the drill rod. Do not use the guard board of the hydraulic breakers as a tool to push heavy objects. Since the excavators and loaders are mainly small machines, they are light in weight. If they push heavy objects, the hydraulic breakers will be damaged if they are light, and the boom of the main engine will be broken if they are heavy, or even the main engine will overturn.

18. When the hydraulic breakers works, it is necessary to press the drill rod on the rock and keep a certain pressure before starting the hammer. It is not allowed to start the hammer in the suspended state.

19. When carrying out breaker operation, do not use the rocking drill rod, otherwise, the main bolt and the drill rod may be broken; do not make the crushing hammer fall down quickly or hit hard stones, which will damage the hydraulic breakers or the main machine due to excessive impact.

20. When the broken object has broken or begins to crack, the impact of the crusher shall be stopped immediately to avoid harmful "air blow". The continuous impact without a target will cause damage to the front body of the hammer and loosening of the main bolt, and even damage the main machine itself.

1. First, read the operation and maintenance manual of the excavator hydraulic hammer carefully to prevent damage to the hydraulic breaker and the excavator, and operate them effectively.

3. When crushing particularly hard or large objects, start from the edge first, and do not continuously strike at the same point for more than 1 min to prevent the hardness of the drill rod head from declining and deforming and the hydraulic oil from overheating.

4. Do not work when the piston rod of the hydraulic cylinder is fully extended or fully retracted, otherwise the shock and vibration will be transmitted to the hydraulic cylinder and thus to the host.

6. Do not carry out crushing operations in water or muddy ground. Except for drill rods, other parts of the excavator hydraulic hammer body should not be immersed in water or mud, otherwise the cylinder, piston and other parts will be broken due to accumulation of mud stains. Hammer damage or even scrap.

9. When the excavator hydraulic hammer is installed and connected with excavators, loaders or other construction machinery, the working pressure and flow rate of the hydraulic system of the main machine must meet the technical parameter requirements of the hydraulic breaker. The "IN" port of the hydraulic breaker is connected with the main engine high-pressure oil. Connection, the "OUT" port is connected to the return line of the main engine.

10. The best hydraulic oil temperature when the excavator hydraulic hammer is working is 50-60 degrees Celsius, and the maximum should not exceed 80 degrees Celsius. Otherwise, the oil seal inside the cylinder will be damaged and the piston of the cylinder will be strained.

11. The working medium used by the excavator hydraulic hammer can usually be the same as the oil used in the main engine's hydraulic system. It is recommended to use YB-N46 or YB-N68 anti-wear hydraulic oil in general areas, and YC-N46 or YC-N68 low-temperature hydraulic oil in cold areas. The filtration accuracy of hydraulic oil is not less than 50μm.

12. The new or repaired excavator hydraulic hammer must be refilled with nitrogen when it is activated, and the nitrogen value should be adjusted appropriately according to the climate environment and working conditions

13. Calcium-based grease or compound calcium-based grease must be used for lubrication between the tail of the drill rod and the cylinder body and the outer jacket, and fill it every 2 hours, and it is sufficient to lubricate each time.

16. When the hydraulic breaker is working, the drill rod must be pressed on the rock first, and the breaker must be operated after maintaining a certain pressure. It is forbidden to start in the suspended state.

17. When performing crushing operations, do not use the drill rod by shaking, otherwise the main bolt and drill rod may be broken; do not drop the breaker quickly or hit hard stones, which will cause excessive impact. Damage to the breaker or host.

18. When the broken object has broken, the blow of the breaking hammer should be stopped immediately to avoid "empty strike". Continuous and aimless blows will cause damage to the precursor of the breaker and loose or short cracks in the main body bolts, which can damage the host itself in severe cases.

19. If the excavator hydraulic hammer is to be stopped for a long time, the nitrogen gas of the rear cylinder should be exhausted, the piston should be pushed into the cylinder, the oil inlet and outlet should be sealed, the rain cloth should be covered, and the surrounding of the hammer should be kept dry.
